This book explains fundamental concepts and useful skills for implementing DevOps principles with containers and Kubernetes. Our journey starts by introducing the core concepts of containers and Kubernetes, and we explore the various features provided by Kubernetes, such as persisting states and data for containers, different types of workloads, cluster network, and cluster management and extension. In order to supervise the cluster activity, we implement a monitoring and logging infrastructure in Kubernetes. For better availability and efficiency, we also learn how to autoscale containers and build a continuous delivery pipeline. Lastly, we learn how to operate the hosted Kubernetes platforms from the top three major public cloud providers.
